MK5 game working

Well its somewhat satisfying to see my first MK5 game up and running....

The image is Queen of the Nile (Brazil), certainly playable despite MAME 0.186 still saying its not working (graphics and sound issues not yet 100%). It just took some time to make sense of the instructions mentioned in my post above, the memory reset is critical.

More MKV games

In order to run the other 3 games each set needs its U7 and U11 roms replaced (and renamed to reflect the original rom that was replaced) with the U7 and U11 roms from the 'qnilebr' set. The U7 and U11 roms are really a 'base' bios and only the Brazilian 'qnilebr' bios requires no continuous com connection to play. In turn it needs a 4 digit security code to be provided to change settings. However once the nvram is setup the games are playable...and stay playable. However the other issue is the MAME GUI does not support running sets with roms that fail a crc check...whereas running the set directly from a cmd box allows you to do this eg. 'mame64 goldpyrb'
The nvram setup is actually straightforward and the same for all 4 games. Once the game image appears along with the error messages press F2 which should take you to a 4 digit security input screen. Press the S key to advance, A to go back the other way and F to input the desired digit. The code is 4856. As you press F for the 4th digit the screen will change. Now SIMULTANEOUSLY press the A and G keys. Now press F2 again and it should take you back to the game and be prompting you (in Portugese) to enter credit! So press the 5 key and then S or D or F or G to place your bet! As the bios is Brazilian this changes some of the language in these 3 games. If it doesn't work the first time, exit, delete the nvram directory for the set and try again.
So thats it as far as MKV playability goes at present, from the documentation on the MAME site its clear significant work remains for the MAME team getting the other MKV games to run.
Still its good to get this far after all the years of work that has gone into this driver!
